What Is This Tool?
This tool allows you to convert between ounces, a common unit of mass, and the UK assay ton (AT), a specialized unit used mainly in assaying precious metals and ore measurements. It is designed to help users translate small mass amounts into industry-standard assay tons used in laboratory and commercial contexts.
How to Use This Tool?
-
Enter the quantity in ounces [oz] you want to convert
-
Select the target unit as ton (assay) (UK) [AT (UK)]
-
Click the convert button to get the result
-
Use the result for assay reporting, metal pricing, or resource estimation
Key Features
-
Converts ounces (avoirdupois and troy) to UK assay tons (AT)
-
Browser-based and easy to use
-
Provides clear conversion results for assay and precious metals industry
-
Supports industry-specific reporting and pricing needs
-
Includes example calculations for quick reference
Examples
-
5 ounces [oz] equal 4.339212723 ton (assay) (UK) [AT (UK)]
-
10 ounces [oz] equal 8.678425446 ton (assay) (UK) [AT (UK)]
Common Use Cases
-
Measuring gold or silver metal content for assay certificates
-
Calculating payable metal values in concentrate or ore shipments
-
Converting historical assay data for resource estimation and accounting
Tips & Best Practices
-
Ensure you choose the correct type of ounce (avoirdupois or troy) based on the material
-
Verify that the assay ton unit is appropriate for your specific assay or commercial application
-
Double-check conversions to avoid rounding errors affecting financial calculations
Limitations
-
The UK assay ton differs from other ton units and is specific to assay conventions
-
Different ounce variants require correct identification for accurate conversion
-
Small rounding deviations can impact economic values in precious metal trading
Frequently Asked Questions
-
What is the difference between an ounce and a troy ounce?
-
An ounce generally refers to the avoirdupois ounce used in common weight measurements, while the troy ounce is specifically used for precious metals and is slightly heavier.
-
Why is the assay ton (UK) different from regular tons?
-
The assay ton (UK) is a specialized unit used in assaying to report ore or metal quantities and does not equal standard long tons, short tons, or metric tonnes.
-
Can I use this conversion for all types of metals?
-
This conversion is primarily intended for precious metals like gold and silver in assay and commercial contexts; it may not be suitable for all metals or materials.
Key Terminology
-
Ounce [oz]
-
A unit of mass in customary systems; common avoirdupois ounce equals exactly 28.349523125 grams, and the troy ounce (used for precious metals) equals 31.1034768 grams.
-
Ton (assay) (UK) [AT (UK)]
-
A UK-specific unit of mass used in assay practice to report ore or metal quantities, distinct from other ton units.
-
Assay
-
The process of analyzing the composition of ore or metal samples to determine the content and value of precious metals.
